ABSTRACT:
A process for producing an olefin polymer which comprises polymerizing an olefin or copolymerizing olefins in the presence of a catalyst comprising a novel solid catalyst component (A), an organometallic compound (B) and an electron donating compound (C) is disclosed. According to the process of the present invention, an olefin polymer excellent in stereospecificity and particle property can be obtained. The catalyst used in the process of the present invention shows a very slight lowering in polymerization activity during a long-term polymerization, and therefore, the productivity of an olefin polymer can be improved.
